CGMiner - huge mining speed?

[flasht]

I changed my GCMiner settings to:

"intensity" : "20",
"vectors" : "4",
"worksize" : "256",
"kernel" : "diablo",
"gpu-threads" : "2"

from

"intensity" : "8",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"gpu-threads" : "2"

And my mining speed changed from about 80Mh/s to about 850Mh/s ... is it even possible? It seems to use much less resources.

May increase a few percent, but not 10 times. Or you have found a way to punish Asic miners with video cards!

This is simply impossible to achieve from the map, it is physically impossible. Yes and burn device can be easily with such loads. Be careful with experiments

Maybe I'm doing something wrong? ckpool shows 0 for my user...

My full config now (350Mh/s):

{
"pools" : [
   {
      "url" : "stratum+tcp://depool.ckpool.org:3333",
      "user" : "*censored*NxuSmHm2DEd8YzYkHK8dQPVs.0",
      "pass" : "x"
   }
]
,
"intensity" : "15",
"vectors" : "2",
"worksize" : "256",
"kernel" : "diablo",
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"shaders" : "2048,",
"gpu-engine" : "0-0",
"gpu-fan" : "0",
"gpu-memclock" : "0",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "75",
"temp-overheat" : "85",
"temp-target" : "65",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "3",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin",
"verbose" : true
}

Does CKPool show something on user stats only when something gets mined? Timeline on graph seems to be right, but it's always showing 0Mh/s.

Or maybe it's because I am using old CGMiner? (the latest Windows binary I could get - 3.7.2)
